An overfill condition of
transmission fluid may cause
shift and/or engagement
concerns and/or possible
damage.

Do not drive the vehicle if the fluid
level is below the hole at the
bottom of the blade type dipstick
(4R70W transmission) or below
the COLD area on the bullet type
dipstick (E4OD transmission) and
outside temperatures are above
10°C (50°F) (see figure to the
right).

Your transmission does not use up
fluid. However, it is recommended
that you check the transmission
fluid at least twice a year. The
fluid level should be checked if the
transmission is not working
properly, i.e., if the transmission
slips or shifts slowly or if you
notice some sign of fluid leakage.

Transmission fluid should be
checked at normal operating
temperatures 66°C-77°C
(150°F-170°F) on a level surface.
The normal operating temperature
can be reached after approximately
32 km (20 miles) of driving.

The transmission fluid should be in
this range if at normal operating
temperature (66°C-77°C
[150°F-170°F]) (see figure to the
right).
